Mathematics

In the given figure $AB || CD$ and $CD || EF$. Also $EA \perp AB$. If $\angle BEF = 55^\circ$ find the values of $x, y$ and $z$.

SOLUTION
Extend BE to G.

Now $\angle GEF = 180^o - 55^o$    Linear pair
$= 125^o$

Also $\angle GEF = x = y = 125^o$    Corresponding angles

Now, $z = 90^o - 55^o$    Right angle
$= 35^o$

You're just one step away
